Documentation: arm: Replace use of virt_to_phys with __pa_symbol
All low-level PM/SMP code using virt_to_phys() should actually use __pa_symbol() against kernel symbols. Update the documentation to move away from virt_to_phys(). Cfr. commit 6996cbb2372189f7 ("ARM: 8641/1: treewide: Replace uses of virt_to_phys with __pa_symbol") Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
